Total incidents attended between 2011 and 2015 (to date) involving people locked in a toilet or bathroom

A London Fire Brigade spokesperson said: "It's embarrassing getting locked inside a toilet but the vast majority of the call outs are not emergencies and we'd like to wash our hands of these incidents, freeing up more time for our crews to assist people in real need of assistance.

"We're asking people to think before they dial 999 and to spare a thought for those who do not have access to sanitation and toilets."

World Toilet Day was created by the World Toilet Organisation to raise awareness for 2.5 billion people who do not have access to sanitation and toilets.
